The network module has modular optics supporting the Cisco pluggable optical modules (POMs) and Cisco Small Form-Factor Pluggables (SFPs), simplifying the selection of network modules from six offerings to one. The SFPs support STM-1 framing standards over multimode, single-mode intermediate-reach, and single-mode long-reach fiber-optic interfaces. The module is a single-port module with LC-type connector. The single-mode SFPs combined with the ATM network module provide high-speed trunking for users with access to a fiber WAN, whereas multimode is ideal for connecting high-speed servers, switches, or hubs equipped with OC-3/STM-1 fiber connections.

Cisco IOS SP Services feature sets are required to support ATM. A maximum of one ATM OC-3 network module is recommended on the Cisco 3825 and Cisco 3925, and a maximum of two ATM OC-3 network modules are recommended on the Cisco 3845 and Cisco 3945

Product Summary

The Network module supports three different SFPs, each with a different physical interface, support OC-3c/STM-1 multimode, OC-3c/STM-1 single-mode intermediate-reach, and OC-3c/STM-1 single-mode long-reach modes, however the module supports ATM OC-3 only. Table 1 lists the SFPs supported on the new network module.

Best-effort service intended for non-real-time bursty applications that do not require a guarantee of traffic characteristics such as bandwidth, cell delay, and cell delay variation.

UBR+

Provides a guaranteed frame rate (GFR) service with single leaky bucket algorithm; provides the ability to reserve UBR bandwidth minimum, or specify bandwidth maximum; similar to VBR in that it increases the minimum cell rate (MCR) when cell rate falls below the MCR.

Employed to maximize bandwidth use of the ATM link by using congestion feedback notification (resource management cells); both PCR and MCR specify the ABR connection; the transmit rate of each connection is flow-controlled such that the rate is always between the user-specified values for a minimum and peak rate.

Compatible with all existing network modules and WICS supported by Cisco 2600/2691/3600/3700/3800/3900 routers
